GUSTAV GOLDSCHMIDT, OF BERLIN, GERMANY.

y METAL COVER Foa BooKs.

SPECIFICATION forming part of Letters Patent No. 465,696, dated December22, 1891.

Application led January 15, 1891. Serial No. 877,915. (No model.)Patented iu Germany August 30, 1888, No. 46,995; in England May 8. 1889,No. 7,420, and in Austria-Hungary September 5, 1889,1To. 21,796 and No.38,684.

To a/ZZ whom, t may concern:

Be it known that I, GUsTAv GoLDscHMIDT, a subject of the Emperor ofGermany, residing at Berlin, in the Empire of Germany, have invented anew and useful Metal Cover forBooks, (for which 1 have obtained a patentin Germany, No. 46,995, bearing date August 80, 1888; in Great Britain,No. 7,420, bearing date May 3, 1889, and in Austria- Hungary, No. 21,796and No. 88,681, bearing date September 5, 1889,) of which the followingis a speciiication.

rlhis invention relates to a metal cover, case, or binding for books andthe like. The back thereof consists of a single piece; and it has forits object greater durability of the binding, and facilitates, moreover,the stamping of title or similar indications upon the back, or it allowsthe back to be perforated in casings for bound books, so that the titlemay be seen. Bindings for books as heretofore made and partly consistingof metal have either had a back of cloth, leather, or the like, andsides of metal or sides of card-board or similar material and a back ofmetal divided and hinged in the middle. v

The annexed drawings show in Figures l to 7 two forms of a metal casingor covering, and in Figs. 8 to 11 a metal binding.

The metal case or covering is so made as 'to be removable, and sorepresented in Figs.

l, 2, 3, 4, 4f, 4b, 5, and 6, and consists of a back u, with which metalcorners b are connected by hinges. rFhe corners h h embrace the coversof the book, as shown in the drawings. Two of the hin ges-say at top andbottom-are fixed, while the other two are so made that when the coversof the book are in a certain position they may be moved, allowing theedges of the parts engaging with the book-covers to be raised clear ofthe latter, so that the entire metal covering or case may be removed. Tothis end the part c of the bottom hinge, fixed .to the back of the coveror case, has a slotf, corresponding to pin d. It is evident that whenpin d and slot f face one another the corner-pieces may be raised so farthat the covers of the book are released. (See the position shown indot-anddash lines, Fig. l.) lVhen the upper corners are released,thelower ones are simply pushed oft the book, and the metal cover orcase is removed from the book.

The operation of removing the metal cover and the construction of thesliding hinge are shown in Figs. 3, 4, and it. Fig. 2 shows a plan of abook fitted with such a case or cover, Fig. 1lb being the back andcorners spread out.

The form illustrated in Figs. 5, 6, and 7 consists of a curved plate ofmetal g, which forms the back, and has perforations or apertures h,showin g the title of the book to which the case is applied. Fixedhinges connect the sides of this case or cover With the back. The sideportionsform a frame open at top and inclosing the covers of the book.The part t' 'of the frame is by a hinge Z lined on the portion 7c of theframe, and a fastening m serves to secure the frame upon insertion ofthe book.

The metal binding for books shown in Figs. 8, 9, and 10 embodies thesaine principle and is extremely simple and durable. Like the case orcover above referred to, covers or sides o o are attached by hinges. Onthe inside of the cover, near to the hinges, a strip of metal is sosecured as to form a slot or recess between the cover and the strip. Thebook, being properly stitched, is secured in the binding as follows: Thecords p, projecting at the sides, as usual, are spread out and securedbetween two strips of card-board q q', Fig. 11, and, if necessary, gluedor cemented thereto. The strips yof card-board, with the cords between,are now inserted between the cover and the inner strip of metal andconnected by punching bosses inthe metal or by rivets, as shown in Figs.8, 0, and 10.

Having now particularly described and ascertained the nature of the saidinvention 'and in what manner the same is to be performed, I declarethat what 1 claim is- 1. In a metal cover, case, or binding for books,the combination of a back a with metal corners b ZJ hinged t the back dand. rigidly secured to the covers of the book, as and for the purposespecified.

2. In combination with the back a, having a hinge c, provided With aslot f, metal corners h h', having hinges c, provided with pins d, asand for the purpose set forth.
